The paper studies the Chongqing hotpot(重庆火锅) and two general types of lead-in phrases(过门) of Chongqing Thumb Fight(划拳). This paper mainly discusses the birthplace and maker of Chongqing hotpot and the origin of the two primary lead-in phrases: Good Brothers(兄 弟好) and Disorderly Chopping Firewood(乱劈柴). The results of studying the Chongqing hotpot and two types of lead-in phrases were found as follows: 1. The Yangtze River is the birthplace of the Chongqing hotpot. 2. The trackers and porters working for the wharves along the Yangtze River create the original Chongqing hotpot. 3. Th encircling rivers cultivate the Good Brothers and the mountainous forests stimulate the Disorderly Chopping Firewood [ABSTRACT FROM AUTHOR]

The aim of this paper is to quantify the socioeconomic impacts of hydropower development to reflect its positive functions from multiple perspectives and dimensions. By applying the multi-regional Computable General Equilibrium (CGE) model to a case study of the Yibin–Chongqing section along the upper reaches of the Yangtze River, the analysis shows that hydropower development has outstanding benefits for the regional economy and livelihood improvement, as proved by various indicators including consumption, investment, GDP, employment, and income. Meanwhile, application of the CGE model provides an effective way to quantitatively assess the socioeconomic impact of hydropower and other clean energy development. [ABSTRACT FROM AUTHOR]

The reservoirs built in the upper stream of the Yangtze River intercept the sediment from upstream, this will decrease the sediment into the Three Gorges Reservoir (TGR) in downstream and slow down the deposition development of TGR. moreover, this also affect navigation condition for a long-term operation. In this paper, calculations are made about the influence of the deposition and navigation of TGR caused by the reservoirs built in the upper stream of the Yangtze River such as Xiluodu and Xiangjiaba Reservoir by using one-dimensional flow and sediment mathematical model. The results suggest that the deposition development in TGR will be postponed with the reservoirs built upstream. Under the condition of the upstream reservoir built, the sediment deposition would not appear at the fluctuating backwater area in the early operation 40 years. Chongqing reach shows scour tendency, deposition basically not occurring in 100 years. [ABSTRACT FROM AUTHOR]

Abstract: the river of Yangtze River in Chongqing area is continuous curved. Hydrology and channel situation is complex, and the transportation is busy. With the increasing of shipments of hazardous chemicals year by year, oil spill accident risk is rising. So establishment of three-dimensional virtual simulation of oil spill and its application in decision-making has become an urgent task. This paper detailed the process of three-dimensional virtual simulation of oil spill and established a system of three-dimensional virtual Simulation of oil spill of Yangtze River in Chongqing area by establishing an oil spill model of the Chongqing area based on oil particles model, and the system has been used in emergency decision to provide assistance for the oil spill response.

The occurrence of organotins in the Yangtze River and the Jialing River in the urban section of Chongqing, China and their impact on drinking water waterworks are reported in this study. Water samples were extracted by solid-phase microextraction and measured using a gas chromatograph with mass spectrometer. The results showed that the rivers studied were polluted by both butyltins and phenyltins and that the butyltin species was the dominant pollutant. Butyltins, especially monobutyltin, were detected in all 18 sampling stations, and phenyltins were detected only in 11 sampling stations. Majority of the organotins were MBTs with concentrations varying from 27.3 to 1,145.8 ng Sn L. Diphenyltin and dibutyltin were the second most common with the highest levels of 113.7 and 202.5 ng Sn L, respectively. Monophenyltin, tributyltin, and triphenyltin had the lowest detection rates with concentration levels of 9.7, 161.8, and 37.2 ng Sn L, respectively. Some of the organotins were also detected in drinking water waterworks, which posed a threat to the water quality of Chongqing. [ABSTRACT FROM AUTHOR]
